Take in account that some authors with Spanish names have `y` as part of their names.

Such authors need to be hardcoded to gnparser, so they do not generate a warning:

{
  "parsed": true,
  "quality": 2,
  "qualityWarnings": [
    {
      "quality": 2,
      "warning": "Spanish 'y' is used instead of '&'"
    }
  ],
  "verbatim": "Aus bus Arango y Molina",
  "normalized": "Aus bus Arango \u0026 Molina",
  "canonical": {
    "stemmed": "Aus bus",
    "simple": "Aus bus",
    "full": "Aus bus"
  },
  "cardinality": 2,
  "authorship": {
    "verbatim": "Arango y Molina",
    "normalized": "Arango \u0026 Molina",
    "authors": [
      "Arango",
      "Molina"
    ]
  },
  "id": "c96d4b75-6604-57c6-be4f-cdfff87f6c65",
  "parserVersion": "v1.7.4"
}
